Star Icosahedron

I have been trying to perfect this design for some time now, and I am finally satisfied with the result. My goal was to incorporate the EZ Star into each of the units, and the great part about this model is that, just like the original EZ Star, more stars can be stacked on top of of one another on each of the units!

Overall, the locks on each unit hold the model together quite well. The inside of the model looks pretty neat too! This is my first modular model, so I would love know what you think of it!
